Problem with Virus on vBB board

[FooFightersLive]

First of all apologies for posting in the wrong section, but i don't see another option. I am not the license holder of the forum with the problem, my friend is, but he is out of the country until September and i can't get his information from him. Therefore i cannot post in any other forum but this.I'm sure you can see that the forum is fully licensed when you view it.

The problem is many visitors are reporting a virus showing on the forum, and i also get a warning from AVG about a virus. It reports it as being in the cache of Firefox and just says:

Threat name: Virus identified Exploit. Detected on Open.

I am an administrator on the board and so i have full admin access, but i have no idea what this problem is or how to fix it. If anyone has any ideas please let me know.

Again apologies for posting in the wrong section but it's the only way i can post on this site until September.

Thanks
Simon

There is nothing we can do about this. We do not have access to all customer sties. The license owner would need to fill out a support ticket.
